T0 ALL WHOM XT MAY COL'GERN:

Be it known that we, WILLIAM S. WBEELI-mend SOLOMON E. BXCKFORD, ofFranklin, in the county ot" Merrimne, end State of Nei;y Hampshire,havel invented certain newand useful improvements in Mitre-Boxes,- ofwhich the following is a. full, clextr, and exact deseription,'referencebeinghad to the accompanying drawings,v making part ofthis'sp'eciticntion, in which- Figure 1 is a perspeiztive View of enrimproved mitre-box.

Figure 2 is n vertical section through the centre of theswingingsow-frame, and the end of the erm which supports it..

Figure 8 is'n sectional detail to be referred to. i

Our'invention consists in a, gnide-frnme for the son', so attached andpivoted to e standard that it can be swung around on an exis vertical tothe pinne on which the work is placed, and clamped et any onglerequired; the guide-freineyitself heingnlso'jointed so thnt it een heinclined to the sai-l vertical axis and clamped in place, thus forming oconvenientmitre-boxv of 'simple construction, in which twoengles ormitre :md bevel can be served :it the sometime. i

To enable others skilled in the nrt to understand and use our invention,we will 'proceed te descrihe the manner in which we have carrieditfont.' Y

In the seid drawings, A is n postor standard, the foot of which issecured to n bench, E, or other suitable pince. This standard isA medein two pieces,v 4 :md-5, one of which, 4, is grooved and slides on theportion, 5, being secured in position nt the required 'height by meansof n screw-bolt, e, which passes through a slot, b, (figs, 1 and 3,) andis furnished Awith n-vvoslier, c. From thel portion L projects on erin,C, of the form shown in tig. 1, the outer end ai being puede circularinthe form of :v1/disk, yand to this portion al is pivoted, by ineensoa. seren'pin,e, the'tep bnr D o? the gnidefrnme E, which carries nsimilar disk,f. At each extremity ofthebnr D is formed nidisk, g, towhich are pivoted the side pieces of the'pilrame E, theextremiti'es .7iof which are of n ferm to correspond with that of the disks y. Thegnidenfrztnre E is bifureated for the reception ef'the smv, (seen in redin iig. 1,) pieces or guides z of nood, or other suitable materiel,being secnred by screws a; to the outside et' the frame so ns to leaveslits 6 of o width to nearly correspondwth the thickness of -thc bladeof the sa-w. By removing these pieces z and slibstitnting others of c,different width, the Width et' the slits d may he varied yfor saws ofvnrious thieitnesses; or it' n smv with n stiff bncl: is to he employed,pieces of n diiereni: form may be used, or the guide-pieces may heprovided with slots, for the passage of the screws x, so that the widthofthe slits Bruay be regulated without retrieving the guide-pieces fromthfrnrneV The gnidefframe E can be raised or lowered, in accordance withthe thickness of the steek to be sawed, b v adjusting the height ci theportion 4 of the standard, ns before explained. To the upper end of thepin e is pivoted en eccentric clamp F, by depressing which theipin e israised, bringing the disk f up against the under sident` the 'disk Ithus lirmly clamping the saw-freine `E at the required angle for themitre to be cnt, which is determined by h Ineens of the graduatedscnlfej on the-,edge of the disk'd, and the pointer la en the bar D. Itis evident that the sco-le may be made on the disk f, instead oi' on thedisk d, if preferred When it is desired to out on a. bevel, thesow-freine llis clamped ot the required angl-ete n vertical. lline'hymenus of o clamp, Goof similar scale Z for the purpose of indicating theanglo. This scale may be ronde a-t either end'of the bnr l), or oneither; of the disks g or h. n

The mitre-hos; above described is simple in its construction :indnotliable lto get out of order, end vili be found extremelvvconvenientfor a greet variety of ivork, as the blade of the sin con be guided withgreat facility hy means of the bfurcnted frame E, so as to out at anydesired angle n mitre orA it bevel, or both simultaneously.

What we Aclaim es our invention, :indde'siro to secure by LettersPatent, is

1. The guide-frnrneE, sb hnngend pivoted to n standard, A, that it conbe swung nronnd en axis vertical t'o the work, and also inclined to thesaid vertical axis, whereby the proper direction con be given to the sawto out. :L mitre or :t bevel, or both simultaneously, suhstnntinlly asset forth.

-2 We also elnirn provdinfc,r the frame E with on index or ndices foriixing or adjusting its position 'around its vertical exis, or nt therequired inclination for n initie or o. bevel, in combination with nsuitable clamp or clamps, or equivalentVincchnnioril device for lookingit when adjusted, substantially ns set forth.
